What is the meaning of the word โ€œinterconnectโ€? As the word is applied in the field of electronics, interconnect, as defined at Techopedia.com, defines the word as follows. โ€œAn interconnect (generally speaking) is a physical or logical connection between two electronic devices or networks.โ€ Printed circuit boards (PCB) consisting of hundreds, sometimes, thousands, of interconnected integrated circuits (IC) and other active and passive devices are essential in todayโ€™s electronic world.
We announced today the extended integration of ScanWorksโ€™ boundary-scan test capabilities with the Teradyneโ€™s PXI Express-based High Speed Subsystem (HSSub). Come see a demo at Booth #101 at the AUTOTESTCON conference!
ASSETโ€™s Michael Johnson presented an update on Non-intrusive Board Test (NBT) at the 13th Annual Board Test Workshop (BTW) in Fort Collins, CO this past week. The overall question posed at the Workshop was, โ€œIs Board Test Losing Relevanceโ€?
The MSP430 is a mixed-signal microcontroller family from Texas Instruments. Built around a 16-bit CPU, the MSP430 is designed for low cost, low power consumption embedded applications. But, does it support boundary scan for board test purposes?
In recent years, the increasing size of flash memory has driven device programming to offline methods. However, new techniques are significantly reducing in-system programming times, making it much more feasible and convenient to program flash memory after itโ€™s already been soldered to the board.
Recently launched DDR4 devices have what memory device vendors may refer to as a โ€œboundary scanโ€ test mode. Even though thereโ€™s not really a boundary-scan function involved on the DDR4 side, this mode actually has been, as claimed by JEDEC, โ€œdesigned to work seamlessly with any boundary-scan devices.โ€ Hereโ€™s a brief introduction to what it does and how to test it with a boundary-scan (JTAG) tool.
